IMPROVEMENT IN SpTUMP-PU LLERS.

Specification forming part of Letters Patent No. 42,095, dated March 29,1864.

To all whom it may concern.-

Be it known that I, JAMES B. LYONS, of Milton, in the town and county ofLitchfield, in the State of Connecticut, have invented certain new anduseful Improvements in Bock and Stump Pullers, andforItemoving andDepositing the Same; and the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, making a part of this specification.

Figure 1 represents a side elevation of the machine. Fig. 2 snows therear end view of the rockpuller. Fig. 3 is a plan or top view' of thewhole arrangement of the machine and cart-wheels.

The object of my invention is to furnish farmers in rough and rockysections of this country with the best and most economical facilitiesfor clearing their land, fitting the surface for the plow and the use ofthe reaper and mowing-machine.

My invention consists in the use and application of the common oX-cartwheels, axle, and neap, in combination with a derrick-frame, windlass,gearing, pulley-block, and hooks, for grappling with, pulling out,moving off, and placing in position for a wall rocksy and bowlders;likewise, the application and combination of two or a double windlass,spur gear-wheel, and sliding pinion, so that by coupling the twotogether an immense power is obtained by applying a small force.-

To enable others skilled in the art to make and use my invention, I willdescribe it in detail, referring to the drawings, and to the lettersmarked thereon.

I use the neap, axle, and wheels of a common ox-cart, the body beingremoved. To the center of the cartaxle X, by the means of a bolt, ring,hook, or clevis and pin, I attach the frame B B, which forms the base orsupport of that portion of the frame to which the windlass K is secured,and which frame B B is also framed in and securely fastened to the twoupright posts A A, that help to make the derrick A A C D. By having twobeams, C and D, framed in near the top of the posts A A, the one abovethe other, the space or opening between them being sncient to admit theplacing of the stationary sheaves or pulleys a ct a in or near the'center, between the upright posts A A. Each side of and between thepulleys a a a are upright pieces b b and divisions c c framed into thecross-beams C and D. Through the posts A A and dividingpieces b b and cc is a strong iron rod or bolt, E, which answers the twofold purpose ofa pin or arbor for the pulleys a a a to turn on, and the clamping of thederrick-frame together by having a washer and screw-nut, e e, on eachend. The derrick-frame may be braced with metal bars d d to the posts AA and beam O, and also braces ff to strengthen the frame B B with thederrickposts A A, in the bottom v of which are strong, broad, solidwheels or rollers F F, to support the weight raised and to move it offfrom the place.

On the top of 'the frame B B, and forward of the derrick, are framed twovertical posts, G G, connected on the top by a. plate of timber, H, on.the top of which are notched two inclined timbers, L L, they being atan angle of about forty-five degrees, and connected at their upper endsto the cross-beam D. At about the middle of the inclined timbers L L, Iplace one windlass, K, to which the rope k is attached that works overthe pulleys a a a and the tackle-block t' i i, to which the grapples Jare hooked to pull up and raise the weight.

On one end of the windlass-shaft K is attached a strong spur-gear wheel,I,.the same having a pawl or dog, g, falling into the cogs of the wheel,to secure it from turning back and holding the weight after it iselevated for moving off. The power is applied to this windlass K by thearrangement of another larger windlass, M, it having on one end of itsshaft m a pinion-wheel, N, which is made to slide on a rib or feather,so that the pinion N can be thrown out of or into gear `with thecog-wheel I. To the large forward windlass, M the rope It is woundroundand fastened, and when drawn out by the cattle that operate themachine it is wound up again, ready v for another pull, by sliding thepinion N out of gear and turning the crank n on the other end of theshaft m. Thus it will readily be seen that an immense power can beobtained with a small force applied to the rope h by the arrangementAand combination of the two windlasses and the blocks and pulleys.

By attaching the machine to the running# gear of the common ox-cart itcan be easily moved with its burden with one yoke of oxen, and the costof the machine will be very muchV diminished.

To operate my improved rock and. stump puller is very simple, it onlyrequiring two men and one pair of oxen. The process is substantially asfollows: The body of the farnrcart being removed, the cattle are hitchedto the neap. The wheels are then backed up to themachine, when it islimbered or connected to the cart-axle. It is then drawn to the fieldand placed in position over the rock to be removed. The pinion is putout of gear and the pawl Athrown back, which will allow the rope tobecome slack, so that the pulleyblock can be lowered and hooked onto thegi apples. The pawl is then dropped onto the cogs of the gear-wheel,which by turning the small windlass, the hooks or grapples are made fastto the object. Then by sliding the pinion into gear and unhitching thecattle from the neap and securing it on the ground by driving a spike orbolt or by sticking a crow-bar through the staple on the end of the neapthen hitch the chain or rope that is fastened to and wound a-round thelarge windlass to the yoke and let the cattle walk ott' in a line withthe neap or pole and a rock of many tons weight will be taken up bodilyand swin g under the derrick. The cattle can then be backed to the ncap,the rope un hitched and wound upon the windlass, the cattle hitched tothe machine, and the burden is ready to be removed and deposited in anyplace desired.

The same process is used for pulling and removing stumps and other heavysubstances.

When a few bowlders or rocks are elevated above the surface so as toobstruct the plow or the reaper or mowing-machine, and they are notwanted for fence, the best and most economical way to dispose of them isto place my rock-puller over them, raise them out of the ground, dig outand deepen the hole suiiicient to bury them beneath the reach of theplow, let them `back again into the earth, and there remain to the endof time.

Having thus fully described my invention, and the modus operandi of thesame, what I claim as new, and desire to secure by Letters Theapplication and use of the oX-cart, neap, wheels, and axle, incombination with a double windlass, pulley-blocks, and derrick-framemounted on wheels, for the purposes herein specified.
